| Abstract | ||
| Pesticide residue levels in water bodies have increased due to the extensive use of pesticides in agriculture. To address this challenge, this study considered the possibility of using biogenic silver nanoparticles (Ag-NPs) embedded in chitosan beads to remove the pesticide. A simple, efficient method was used: Ag-NPs (diameter range: 8.02 to 27.2nm) were biosynthesized by Fredinandcohnia onubensis and then immobilized on chitosan to remove the permethrin from aqueous solutions. At 90%, the resultant chitosan silver nanoparticles composite (CS-Ag-NPs composite) showed a remarkable adsorption capacity. To be more precise, 1g of CS-Ag-NPs composite efficiently eliminated 90% of permethrin from a 25mL pesticide solution (0.1mg/ L) under controlled circumstances (35°C, pH 7-, and 60-minutes shaking). These results demonstrate the potential of Fredinandcohnia onubensis-biosynthesized CS-Ag-NPs composites as a novel, biocompatible, and eco-friendly method for the removal of pesticide in water treatment applications. | ||
